And since you are writing about magnetospheres, rotational arcs and Van Allen [anti] radiation belts I will say it again, for my part: IT DOES'T MATTER.
There's not a DARN thing you or I can do about it so why get your shorts in a bunch all hot and bothered about it?
It would matter if the protection provided by the earth's magnetosphere we have long been enjoying (without knowing much about it) were to fail. But as I tried to explain, it's my opinion that is not likely to occur unless the earth also somehow (for reasons unknown to myself) were to begin radically wobbling off-kilter, which would likely mean humans on this planet if, or when things like that were to occur would have other big problems, too.
Who's saying I'm all hot and bothered? You? Your assumptions, and then the judgments you make based much upon those assumptions --suck. Really, they do. I'm not hot about much of anything concerning this...just pointing out how vapid your own remarks were.
